The APR Throttle Booster app allows you to wirelessly tune your vehicle’s throttle pedal for an instant response and finely tuned sensitivity to your desire. The app comes pre-loaded with 5 preset throttle response curves. Optionally you can tune the profile on your own. Go soft or lightning-fast – it’s your choice! This all works via Bluetooth to the APR Throttle Booster Module. It plugs into your factory throttle harness and then communicates wirelessly with the app and the included wireless switch, giving you multiple methods to quickly change profiles. With most vehicles on the market today offering such an undesirable throttle pedal response profile, you’ll love having the ability to adjust it on your own. And don’t worry, our intuitive guides and tutorials make adjustments a breeze! Go APR!
